Utilization of Afzelia africana Sm. ex Pers. (Magnoliopsida: Fabales: Fabaceae) in Nigeria and its implications for conservation

Abstract

This study investigated the ethnobotanical uses of Afzelia africana Sm. ex Pers., a threatened tree species in Nigeria to determine the impact of uses of this species on the risk of its extinction. Ethnobotanical surveys were conducted by means of semi-structured questionnaires with the local community called Ijebu Igbo in Ogun state of Nigeria and a total of 60 respondents were interviewed from this community. Herbalists, artisans, Islamic scholars, traders, and retirees were interviewed to document their knowledge of the uses of A. africana. This study revealed that there are different uses of A. africana, among which its spiritual and medicinal uses were the most dominant. An unsustainable harvest of A. africana for these uses will aggravate the decline of its population, thereby increasing the risk of extinction. This study recommends local awareness of the indigenous people of possible ways this species can be utilized in a sustainable manner to prevent its extinction.
